+
+ SMPI:
+ * Implement some more MPI primitives:
+ MPI_Waitany, MPI_Waitall, MPI_Allreduce
+
+ SURF:
+ * Extract the routing logic into its own object.
+ (was dupplicated in network.c and workstation_LV07.c;
+ Allows to implement other ways of storing that info)
+ => kill now useless network_card concept
+ - Use dynar to represent routes (instead of void** + int*)
+ - kill link_set (use surf_network_model->resource_set instead)
+ - Add a command-line option to choose the routing schema to use
+
+ * Simplify model declaration
+ (less redirections, less function to write when defining a model)
+ - Factorize stuff between models:
+ - model_init/exit
+ - Set of resources:
+ surf_model_resource_set(model)
+ surf_model_resource_by_name(model, name)
+ - Unify the types of models in s_surf_model_t (using an union)
+ - Embeed fields of common_public directly into s_surf_model_t
+ - Rename model methods:
+ action_free ~> action_unref
+ action_change_state ~> action_state_set
+ action_get_state ~> action_state_get
+ - Change model methods into functions :
+ (model)->common_public->action_use ~> surf_action_ref
+
+ * Implement a generic resource; use it as ancestor to specific ones
+ (allows to kill duplicated code in models)
+ Drawback: timer command don't need no name nor properties;
+ workstation_CLM03 don't need no properties
+ (but I guess we can live with those few bytes wasted)
+
+ * Improve the action object model
+ - implement a constructor avoiding dupplicated code about field
+ initialization in generic_action part.
+
+ XBT:
+ * Add xbt_set_get_by_name_or_null() [Silas De Munck]
+ * Add xbt_graph_node_get_outedges() [Silas De Munck]

OVERALL CHANGES:
- * Also include strbuff from xbt.h public header
-
+ * Implement a --cfg-help to show existing configuration variables
+ * Build chain do not require doxygen in maintainer mode
+
GRAS:
* fix a bug on struct sizeof computation, which prevented the
exchange of arrays of structs in some conditions
-
+ - added a regression test about this in datadesc_usage
+ * Allow the exchange of 0-long dynamic vectors.
+ - for that, use -1 as indicator of dynamic size instead of 0
+ - This implied to change any size from unsigned long to long,
+ reducing a bit communication abilities, but I guess that with
+ 64bits being quite common, this is more than enough.
+ - This also induce a protocol change, thus bumping network protocol
+ version from 0 to 1 (if we have external users, we have to get
+ clean on that point too ;)
+ - added two regression tests about this in datadesc_usage
+ * Be more verbose when propagating local exceptions
+ This helps debugging.
+ * Display the status of simulated processes when receiving SIGINT in
+ simulation mode
+
MSG:
* Allow to control the simulation from a trace file.
New functions MSG_action_register() and MSG_action_trace_run()
triggers the corresponding actions within the system.
For now, only a toy example is provided in examples/msg/actions
* Add an exemple of process migration in examples/msg/migration
-
+ * Fix a bug in task exchange which broke MSG_task_get_sender()
+ Add a teshsuite regression test for that.
+ [Bug: if MSG_task_get_sender() is called after sender exit,
+ bad things happen]
+ * Fix a bug which prevented suspend/resume to work properly
+ * Display the status of simulated processes when receiving SIGINT
+ This fixes a regression of v3.3. due to the introduction of SIMIX
+ * Bug fixing in failure management:
+ - trace could not start by a failure at time 0
+ - failure during communications were not working
+
SIMIX:
* Add SIMIX_process_set_name() to change the name of the current
process in the log messages.
+ * Store smx_hosts in a dict since we only retrieve them by name
+ * Move the configuration infrastructure to surf
+
+ SIMDAG:
+ * Move the configuration infrastructure to surf
+
+ SMPI:
+ * Massive internal cleanups:
+ - Store internal structures on processes instead of hosts (allows
+ to have more than one process per host, in addition of being more
+ logical)
+ - Cleanup the initialization/finalization process
+ - Kill a whole bunch of unneeded synchronization:
+ processes run in exclusive manner within the simulator
+ - Move queues from global tables to process data fields
+ * Improve smpirun:
+ - now accept -platform and -hostfile arguments
+ - Pass the right rank value to processes according to the hostfile
+ * Compile the examples by default, and use them as regression tests
+ * Implement MPI_Wtime()
+ * Change the reference speed to a command line option
+
+ SURF:
+ * TCP_gamma can now be specified as command line option using
+ --cfg=TCP_gamma:10000000.0
+ * Change the --surf-path cmd line option into --cfg=path:
+
+ XBT:
+ * Also include strbuff from xbt.h public header
+ * xbt_ex_display(): do not free the exception after displaying
+ This allows to do more with the given exception afterward.
+ Users should call xbt_ex_free() themselves.
+
+
+
+ Portability report of this version:
+ * Main portability targets:
+ - Linux(debian)/x86/context
+ - Linux(debian)/x86/pthreads
+ - Linux(debian)/amd64/context
+ - Linux(debian)/amd64/pthreads
+ These targets fail about 1/10 of times on gras/pmm, but we believe
+ that this is because of the test, not because of simgrid.
+ amok/saturate_sg fails even more rarely, and the test may not be
+ the problee.
+
+ - Mac OSX Leopard/x86/context
+ The test suite still spits tons of errors because some obscure
+ force prevents us from removing the temporary directories
+ arguing that they still contain some metadata I've never heard of.
+ Smpi fails because seq is not installed.
+ Everything seems to work properly beside of that.
+
+ * Exotic platforms:
+ - AIX version 5.3 (both contexts and pthread)
+ Smpi still fails there because mktemp is not installed.
+ XML inclusions seems rosty on AIX.
+
+ * Windows: it's still lagging behind. If you want to help, please
+ stand up.

For information, the beginning of coding on GRAS was back in june
2003. I guess that every line has been rewritten at least twice since
